CVE-2024-37166 | BDVDB-2026-239042 Detail

gurgundayghtml

Description#

ghtml is software that uses tagged templates for template engine functionality. It is possible to introduce user-controlled JavaScript code and trigger a Cross-Site Scripting (XSS) vulnerability in some cases. Version 2.0.0 introduces changes to mitigate this issue. Version 2.0.0 contains updated documentation to clarify that while ghtml escapes characters with special meaning in HTML, it does not provide comprehensive protection against all types of XSS attacks in every scenario. This aligns with the approach taken by other template engines. Developers should be cautious and take additional measures to sanitize user input and prevent potential vulnerabilities. Additionally, the backtick character (`) is now also escaped to prevent the creation of strings in most cases where a malicious actor somehow gains the ability to write JavaScript. This does not provide comprehensive protection either.

Impact#

Per CVSS v3.1: confidentiality impact high, integrity impact high, availability impact low. Attack vector: network.

Weaknesses#

  • CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
